Tire tread



FIG. 1 is a perspective view of a tire tread showing our new tire tread design, it being understood that the tread pattern is repeated uniformly throughout the circumference of the tire tread with the opposite side being the same as for the side shown; and,

FIG. 2 is an enlarged fragmentary front elevation view of our new tire tread thereof.

The broken line showing of a tire sidewall and inner bead is for illustrative purposes only and forms no part of the claimed design.

In the drawings, the dark stippled surface shading represents the recessed portion of the tread grooves, having a depth as best shown along the right edge of the tread in FIG. 1. 

The ornamental design for a tire tread, as shown and described.
